The KleenBore® Chamber Flag can be used for Semi Auto Handguns (.40 Cal./.45 Cal./9mm/10mm).

It allows for you to stay safe on the range, in the field, or while hunting. When transporting/storing your semi-auto handguns, a chamber flag indicates the firearm is clear and no round can be chambered. This adds an extra layer of security when handling the firearms.

Made of highly visible and rugged nylon material for durable use. It can also be conveniently kept on your key chain for easy access!
